“…In [34,32,9,36] issues and challenges related to identification and trust are raised by the authors. Employing smart contracts, and having an access to the distributed ledger, in addition to addressing the issues just mentioned above, could also provide a simplified solution for a distributed master-less reputation management as stated in [15].…”

“…The majority of the papers focus on collaborative governance and trust and reputation management. Among the applications, the following use-case scenarios are elaborated the most: an approach for energy trades in an open P2P market, while insuring anonymity and security of the participants [7]; a prototype of a system for blockchain-driven self-aware agents-assisted contracts [31], a distributed multi-level reputation scoring system implemented into P2P clusters [15]; trust management for both supply-demand relationships [35], and for the process of software verification [34]. In a more orthogonal position, [13] reveals a number of challenges, potential difficulties, and pitfalls that have to be considered when applying BCT.…”

“…For the transactive energy system proposed in [7] Kvaternik et al employ a decentralized computation fabric based on Ethereum, a novel trading sequence implementation (including fulfillment of partial trades), as well as off-blockchain communications. Kiyomoto et al [15], in the framework of multi-level scoring systems for P2P clusters, employ BigchainDB [39] --a technology that combines the properties of decentralized processing platforms like Ethereum, and decentralized file systems like Inter-Planetary File System (IPFS). The authors assume that in the MAS the agents are not trusted i.e., each node can play his own game.…”

“…For example, cloud computing systems dealing with potentially "very large datasets" are going towards a process of agentification, exploiting the crucial support of blockchain technology [8]. Considering agents as atomic entities populating P2P communities, the design of a fair scheduling and a general protection of the whole cluster against abusive or malfunctioning nodes is currently one of the main challenges [15]. In particular, in distributed master-less systems with reputation rating across the cluster, the application of multi-level principles of cryptocurrencies has given insightful results [15].…”

In fact, in [14] it is demonstrated that by combining peer-to-peer networks with cryptographic algorithms a group of agents can reach an agreement on a particular state of affairs and record that agreement, without the need for a controlling authority.…”

Multi-Agent Systems (MAS) technology is widely used for the development of intelligent distributed systems that manage sensitive data (e.g., ambient assisted living, healthcare, energy trading). To foster accountability and trusted interactions, recent trends advocate the use of blockchain technologies (BCT) for MAS. Although most of these approaches have only started exploring the topic, there is an impending need for establishing a research road-map, as well as identifying scientific and technological challenges in this scope. As a first necessary step towards this goal, this paper presents a systematic literature review of studies involving MAS and BCT as reconciling solutions. Aiming at providing a comprehensive overview of their application domains, we analyze motivations, assumptions, requirements, strengths, and limitations presented in the current state of the art. Moreover, discussing the future challenges, we introduce our vision on how MAS and BCT could be combined in different application scenarios.technical and scientific challenges. Despite many attempts and previous works aiming at developing models and mechanisms to guarantee communications security and trust in MAS [4,5,6], such requirements have not been fully satisfied yet.Recent trends [7,8,9,10] nourish the promising idea of integrating MAS and blockchain technologies (BCT) [11,12], with the expectation of providing BCT features in use-cases where agent systems require them. However, employing a new technology such as blockchain "as-is" and by itself in dynamic and quickly evolving scenarios can represent an unlucky choice. This may be due to several reasons, spanning from fundamental properties of BCT, to application/domain specific constraints. As an example, consider the modification of blockchain code, which can happen through majority consensus. Reaching consensus in a distributed multi-stakeholder network with possible unaligned interests can be considerably complex, and new issues might be introduced as a result [13]. Although effective, some strategic decisions can hinder the evolution of the technology from academic institutions to real-world problems [14].Nevertheless, combining BCT and MAS can represent a win-win solution if properly managed: On the one hand, the adoption and adaption of BCT may fix the security limitations broadly known in MAS literature. On the other hand, BCT can also contribute with features missing in some MAS scenarios (e.g., flexibility). For example, cloud computing systems dealing with potentially "very large datasets" are going towards a process of agentification, exploiting the crucial support of blockchain technology [8]. Considering agents as atomic entities populating P2P communities, the design of a fair scheduling and a general protection of the whole cluster against abusive or malfunctioning nodes is currently one of the main challenges [15].
